You want to ignore God, go ahead but be advised you are rationalizing and making the words mean what you want them to mean. Its folks like you that rewrite the bible so that it supports homosexual behavior, abortion etc.
In Exodus 22:19 it says, "Anyone who has sexual relations with an animal must be put to death." and 20 "Whoever sacrifices to any god other than the Lord must be destroyed."
Lev. 19: 27 says, "Do not cut the hair at the sides of yur head or clip off the edges of your beard."
Do you follow those rules as well? Or are you selective when it comes to following the rules of the OT? I could give you more examples, but I think you get the idea. If you shave are you going against God? Of course not. THe point is as I said before.
The reason scriptures say that about aliens is to show that those that follow God are a generous and caring people. It is to show that GOd is a benevolent God.
It does NOT mean that we should be over run with those chosing to break our laws.
